PackagesNotFoundError：当前渠道中不提供以下软件包

Question

我正在尝试在 python 中安装 ngram，但它给出了错误。我尝试了这些代码，但它们又都给出了相同的错误：

conda install ngram

第二：

conda config --add channels loopbio
conda config --append channels conda-forge
conda install ngram -c conda-forge

错误是：

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - ngram

Current channels:

  - https://conda.anaconda.org/conda-forge/noarch

我该如何解决？

我也试过

pip install ngram

Answer 1

在 anaconda.org 上搜索显示该软件包不在您搜索的任何频道中。ngram 包的pypi 页面显示它与 Python 2.6、2.7 和 3.2 兼容。如果您使用的是 Python 3，很可能您使用的是更新的版本，例如 3.5 或 3.6，该软件包似乎不支持该版本。您可以尝试通过从github下载并运行python setup.py install.
